Mini Tutorial: Read file contents in C

[Dangermouse]

basically this is a function where you pass the filename and it will print out the file contents (I know, not very useful but this has taken me an hour to figure out lol)

I hope the comments are enough


void getFileContents(char *fileName)
{
/* fp = file pointer, open the file name in read mode */
   FILE *fp = fopen(fileName, "r");
   
   /* Number of bytes */
   int fSize = 0;
   
   /*Current character read*/
   char fChar;

   /* File buffer, will hold the data in the text file */    
   char * fBuffer;

   /*If we opened the file*/
   if (fp != NULL)
   {
    /*Read each char until end of file*/
       while ((fChar = fgetc(fp)) != EOF)
       {
      fSize++;
       }
       
       /* Rewing to beginning of file */
       rewind(fp);

       /* read fSize number of bytes from file pointer (fp)*/
       fread(fBuffer, 1, fSize, fp);
       
       /* Append a null terminator to make it a string*/
       fBuffer[fSize] = '\0';
       
       /* Print the file data */
       printf("%s\n\n",fBuffer);

       printf("File size: %d bytes\n", fSize);
   }
   else
   {
    /* Print the fopen error */
    perror("fopen");
   }
   
}


And use it likebr]

char fName[] = "C:\\test.txt";
   getFileContents(fName);
